To interface my own acquisition software directly with Labview_DLL.dll, I have seven steps to go. But I am confused with the fifth step, generate a file pointer.
Biosemi tells me that Call READ_POINTER to generate a file pointer. Inputs are "handle" (from step 1), and "pointer (0). Output is a "pointer". Use this parameter as a file pointer.
I can't understand the meaning of READ_POINTER with my limited knowlege. Is READ_POINTER used to read datas in ringbuffer?
READ_POINTER gives you the location in the ringbuffer where new incoming data is written. The acquisition program should use the outcome of READ_POINTER to know if new data is ready to be read from the buffer, and where this new data is located in the ringbuffer.
